Four years ago I bought an inexpensive but highly-rated pair of "TrailBuddy" trekking poles from Amazon. They're not titanium or graphite, but they were only $32. I use them snowcamping every winter, and they've worked perfectly.
Right before Trump's China tariffs kicked-in I spotted--on Temu--the same trekking poles, but selling under a different name. I bought multiple pairs so that I could offer them to friends.
My friends now have what they need, so I'm selling the remaining 4 pairs for $25 each. (Look on Amazon for "TrailBuddy trekking poles" and you'll see that they're selling for $41 to $50, + tax.)
In the photos below, I'm showing what comes in the package - it includes two poles, multiple ends and cups, and a black bag for storage. The yellow pole is not for sale; it's my 4-year-old TrailBuddy. Look at the photos and you can see why I am confident the off-brand poles I have are TrailBuddy poles.
I've also added a photo of me using my Trailbuddy poles under conditions when a pole failure would be catastrophic. Photo taken at Crater Lake, last April, crossing the west side of The Watchman.
